Renault will announce its next engine supply deal "within a matter of days" and confirm its full line-up for the 2014 season by the end of June as it prepares to split with Williams.

Renault currently supplies four teams on the grid - Red Bull, Lotus, Williams and Caterham - and it has confirmed it will continue with Red Bull next year while taking on a new partnership with Toro Rosso. Williams has signed a deal to switch to Mercedes power under the new engine regulations next year, while Caterham has confirmed it intends to continue with Renault and Lotus is expected to stick with the French manufacturer too.

President of Renault Sport F1, Jean-Michel Jalinier, said his company had been prepared to supply five teams in 2014, but the departure of Williams "normalizes" the situation.

"For Renault Sport F1, we have stated on numerous occasions that we would supply up to five teams if there was a requirement to do so, but this would not make sense economically or be ideal for our resources," Jalinier said. "Three, or up to four, teams is the ideal for us so the departure of Williams normalizes the situation and makes things much clearer from our side. We will announce the next team within a matter of days, and then confirm the final stage before the end of June. We remain incredibly motivated about the challenge of the 2014 engines."

Despite historic links between the two companies, the most recent Williams-Renault contract lasted just two years. But Jalinier said they were parting ways on good terms.

"'We would like to thank Williams for the warmth it has extended to Renault over the last two years and wish the team the very best for the future," he added. "Williams and Renault have a long history together and quickly recaptured its winning spirit in the early days of the rekindled partnership with victory in Spain 2012. We will continue to actively work with the team until the Brazilian Grand Prix in November to end the second incarnation of the partnership with results that do justice to its reputation."
